Thanks for the reply, the reason that I asked was that when we get to our destination and adjusting the pressure, I am quite surprise how much they drop. My tow car is a Mondeo 2. 0 TDCI, and I noticed then when I am just using the car for normal use I had to constantly top up the pressure quite regular, I was told by a tyre dealer it was quite common problem with Fords so I was advised to have the tyres glued sealed rather than use washing up liquid when having tyres fitted.
Hello We brought our first caravan in Sept 2013, before I hitch our car to the caravan I would increase the tyre pressures as per the heavier load. Is this correct way, or would you hitch the caravan then increase tyre pressures. Appreciate any advice given.
